Abstract
An airbag deployment rate sensor employs a tape or string that is wound on a spool and connected to the fabric of an airbag cushion so that as the airbag deploys, tape or string is pulled from the spool causing it to rotate. A brake is applied to the spool to prevent the buildup of momentum and so the tape and the spool will come to a rapid stop when the tape is no longer being withdrawn from the spool because the portion of the airbag to which the tape is connected has collided with an object. A sensor is positioned to detect rotation of the spool and so to monitor the rate at which tape or string is being withdrawn.
